Android how to load Image file with different extension using Picasso

This is a different situation. I want to load a image file which has stored with different extension like 'photo.xyz' instead of 'photo.jpg or photo.png' using Picasso. to avoid image from gallery i am storing image like this. Please help me is there any option to show like this.

Neither Picasso nor Android (which does the actual image decoding) cares what the file name is. It can be anything. The type of the image is always determined from the first few bytes of the actual image data.

As a small workaround you can programmatically put .nomedia file into your app folder to prevent images to be cached by mediaserver and displayed in a Gallery app.

Create image gallery using image paths stored insqlite db

I am creating an app which i want to use to report field incidences at work.
Each incident may have one or more photos.
At this stage, i want to store the images locally on sd card and store their paths in the sqlite db.
So far i have figured out the db design and how to capture and save images on sd card and store their paths in the db.
What is challenging me now is how to dispay the images back?
I want a set up that dispalys the incident description and the associated image(s).
I have created xml file with textview to display the incident description and a gallery to dispaly images related to that incident.
My question is how to use image paths to create a gallery...or a better suggestion...
I have written code to retrieve incidences and related images ...

Because when every app have some limitation regarding Heap allocation.... when u load images more than allocated heap space it will throw out of memory exception....

Use a Grid View or PageViewer to display a gallery. The one thing you have to do while using this is Memory management.

Android: Hardcode images with paths

I am working on an a simple android application that stores objects in an array, and displays them to the user via a listview. Each object contains a photo and a single text field. For demonstration purposes, I would like to pre-populate this array with some hardcoded objects.
The trouble is that the images are typically acquired through the camera interface, and each object only stores the path to that image. I can add the hardcoded images as drawables, but then they don't have a file path. I could when the app is initialized, convert the drawables to bitmaps and save the bitmaps to the SD card, but that seems too complicated to be the correct answer...
Any ideas on the best way to get these images into file storage so that I refer to them via their URIs?
Thanks!

When you create your views in your adapter, have a ImageView in your layout and use a loader or custom AsyncTask to load the image in the background and have it update the ImageView instance once it has the data.

check the background from this on loading images from the network.
You acquire images from the camera but notice that when you do a resource chooser where mimetype = img/*, the selector just merges local camera(gallery) storage with other photo, content providers. An example of common chooser for photos is in 'Evernote' where you go to the composer view with the 2X2 grid and touch the 'attachment' icon... thats a photo chooser...
In other words , it helps to understand the general practice for managing photos and for presenting them in imageViews.
Typically, there is a lazyLoader that has an interface with args for the imgView and the URI of the image source. Under the covers on a call to 'loadImage(view, uri), the implementation checks the following:
is the bitmap already in a memCache?
the local file , that backs the bitmap, does it exist in the folder reserved for this purpose?
if none of above, go get the array of bytes for the img from across the network ( or in your case , get bytes from camera ).
Even though your question is a little different , IMO , the standard practices for images may apply and you may want to adapt one of the many libs for image presentation to your specific requirements.

Android Efficient Bitmap processing

My scenario:
In my activity, I have to show 2 galleries, 1 with large image and another is a thumbnail(same exactly like default Gallery application).
My doubts:
I am planning to save as 2 images(1 with large size and another one with thumbnail size) in sdcard for fast processing. Is that good practice? since it will increase the size.
Or Shall I resize the large image during the getView method of BaseAdapter to small size for displaying in thumbnail gallery?
Which one is the good practice? I don't want to slow down my app.

See this example.
I will suggest you that, put only your large image inside your sdcard. But at runtime, Android provides a good facility to get Thumbnails using MediaStore.Images.Thumbnails.
Edit:
You can also get use Loading Sample Sized Bitmap. This will first create a sample size of your requirement. Then will give you a Thumbnail sized Bitmap.

ACTION_VIEW for images but only a subset of images

I have an app that have more than one gallery. It is a travel app and it have a separate gallery for each trip. When I'm taking pictures with the camera I'm saving them in the default MediaStore of the system.
To view an Image I'm using new Intent(Intent.ACTION_VIEW) and it launches the default image viewer. When scrolling with the left and right arrows it displays all the pictures in the folder where the pictures from the camera are saved.
Is there any way to put an extra in the intent when calling VIEW action which images to scroll trough? I have the IDs of the images for a certain trip in a database.
Or putting them in a separate folder is the only solution?

You could also consider building your own preview activity using a GridView. Of course this is more work to do, but also offers more flexibility:
You can create "virtual" folders
You can display images from local store or from the net (if you want to offer synchronization with web albums for example)
You can highlight certain images (favorite, shared)
